Hi doctor, I had a bad accident a month ago and fell hard on my upper back and head , since then i have had strange sleeping patterns from insomnia with no sleep for days to constantly fatique. I have had severe headches to the point where my vision is impaired, constant nausea and im having extreme hairloss to where its actually caused balled spots, i went to a gp that thinks it may be shingles since i ve had that many times in the past. I also been getting strange sores on my skin in sensitive areas and im constantly dehydrated after drinking loads of water. I am 22yrs of age. Please help.
